Western Interior Cretaceous Project (WIK): North-South Stratigraphic Section along Geographic Center of Basin

FOUCH, T. D., T. S. DYMAN, and C. M. MOLENAAR, U.S. Geological Survey, Denver, CO, F. G. ETHRIDGE, Colorado State University, Fort Collins, CO, and R. J. WEIMER, Consultant, Golden, CO

This stratigraphic section extends from central Montana through the Powder River, Denver, and Raton basins to the San Juan basin of New Mexico. Four east-west sections across the Cretaceous basin, presented at this meeting, are tied together along the geographic center of the basin where the strata are largely marine in origin.

Lithostratigraphic, chronostratigraphic, and sequence stratigraphic data are presented.
